File system encryption in Alpine Linux
This is similar to my previous article Encrypting Filesystem in Void Linux but for Alpine Linux The point of this recipe is to create a encrypted file sytem so that when the disc is disposed, it does not need to be securely erased. This is particularly important for SSD devices ...
Desktop Environments 2023
Around April 2023, I decided to look for a new Linux Desktop Environment for my personal void linux. So I tried these distros: lxqt: This is the one I eventually chose to switch to. I liked it that it was very small and light, and very modular, almost like a kit that you assemble yourself. Because I have thinking for some time that I would like to make my ...

So naturally, I decided to switch to KPN's native IPv6 service. They provide a /64 prefix, which is reasonable. Would be better ...
Encrypting FileSystem in Void Linux
The point of this recipe is to create a encrypted file sytem so that when the disc is disposed, it does not need to be securely erased. This is particularly important for SSD devices since because of block remapping (for wear levelling) data can't be overwritten consistently. The idea is that the boot/root filesystem containing the encryption ...
